As she embarks on her massive comeback tour, Britney Spears is hopeful to have her boys Sean Preston and Jayden James along for the ride. But according to Kevin Federline's attorney, nothing has been set in stone just yet.

Kevin Federline has been keeping under the radar recently while his ex-wife Britney Spears has been getting all of the attention. He has been called many things in the last five years, from gold-digger to wannabe and partier, but lately he only answers to the name "Daddy".

Everything is falling into place for Britney Spears' big comeback tomorrow, with the release of her new album Circus. And yesterday (November 30) her sons Jayden James and Sean Preston were spotted arriving at Newark Airport in preparation for the big event.

The two toddlers were picked up by Brit’s parents Jamie and Lynne Spears following their Transamerican flight from their home in Los Angeles, California.
